Font Licensing Calculator

A font licence prices three things at once: how many typefaces are being licensed, how many people will use them, and what those people are allowed to do with them. The last of those is where the cost usually hides, because a licence bought for print does not cover a website, and neither covers an application that ships the font file to every install.

The seat count does most of the work in this model. At the default figures, ten fonts at 50 each gives a base licence of 500, and five users at 50% extra per additional seat adds 1,000 on top, so two thirds of the 1,500 total comes from seats rather than from the fonts themselves. Turning web use on adds a further 500 at a 100% premium, taking the total to 2,000 and the effective cost to 200 per font. Web use is off by default, which is why the headline figure reads 1,500 rather than 2,000.

Free and open licensing is the other half of the picture and it is not a lesser option. The SIL Open Font License is a community-approved open source licence written specifically for fonts, and fonts released under it can be used in books, posters, logos and on websites with no acknowledgement required, and bundled into applications subject to stated conditions. That last point is worth noting against commercial terms, where application embedding is commonly a separate licence at a multiple of the desktop price.

One structural caution applies wherever the fonts come from. Copyright is national law, and what is protected differs between countries: the font file is generally protected as software, while protection for the typeface design itself varies by jurisdiction. The World Intellectual Property Organization sets out how copyright works across its member states, and the practical consequence is that a licence bought in one market does not automatically describe the position in another.

Quick example

With a fonts count of 10, a licence of 50 per font, 5 users, an additional-user rate of 50% and web use off, the result is 1,500.00. The breakdown shows a base licence of 500, multi-user cost of 1,000, no web premium, and an effective 150 per font.

Switch web use to 1 and the same licence becomes 2,000, or 200 per font. Nothing else changes; the premium applies to the base licence rather than to the multi-user total, which is why it adds 500 rather than 1,500.

Which inputs matter most

Fonts count and licence per font move the total in exact proportion, since both scale the base that everything else is calculated from: a 1% change in either moves the result 1%. They are interchangeable in the arithmetic, so ten fonts at 50 costs the same as five at 100.

Seats are the sharper lever. The additional-user percentage moves the result 0.67% per 1% at the defaults, but adding a single user moves it 16.67%, from 1,500 to 1,750. Turning web use on moves it 33.33% in one step. Those two inputs are where the answer actually changes.

The user model is linear and has no ceiling, which is the assumption to watch. Each extra seat adds the same percentage of the base licence as the one before it, so at the default 50% rate five users cost three times the base, ten users cost 5.5 times, and twenty users cost 10.5 times, which on a 500 base is 5,250. Commercial licences are usually banded rather than linear, with the marginal cost per seat falling inside each band, so this model tends to overstate at higher seat counts unless the additional-user percentage is lowered to reflect the band actually being bought.

What is happening under the hood

Base licence is fonts multiplied by the price per font. The multi-user cost adds that base again for each user beyond the first, scaled by the additional-user percentage. The web premium, when web use is switched on, is a percentage of the base licence. The three are summed, and the effective cost per font is the total divided by the font count.

Two things the model does not represent. It applies no volume banding, so per-font and per-seat rates never step down with quantity. And it treats every font as carrying identical terms, when in practice a family bought as a package is usually priced differently from the same number of unrelated faces, and different foundries define a seat differently. Licence term, renewal, support and any separate rights for applications, broadcast or ebooks sit outside the calculation entirely.
